We had something to pick up in Wilno and a delivery to make to Killaloe, so we made a little holiday of it, a break from the nursery, having a nice picnic at Golden Lake, and lovely walk in a bit of publicly accessible alvar at the Fourth Chute.

Here are some photos of some spring wildflowers growing in their alvar habitat in the Ottawa Valley. The featured photo above is Small Skullcap (Scutellaria parvula). All these little known wildflowers are truly lovely additions to sunny rock gardens, especially if the garden is built with limestone rocks (or marble or dolomite or urbanite* – all calcium carbonate rocks).

Rock Sandwort (Sabulina michauxii, formerly Minuartia michauxii) growing in a little alvar near the Fourth Chute of the Bonnechere River.
Hairy Beardtongue (Penstemon hirsutus) growing in its alvar habitat.
Seneca Milkwort (Polygala senega).
Balsam Ragwort (Packera paupercula). This bright flower is a true alvar indicator plant. However, its strict need for a limestone substrate and its biennial nature make it a difficult subject for our nursery. We do carry the closely related perennial Golden Ragwort (P. aurea) – a bigger plant, for moist sites.
